Marriage Markets in Bolivia


If people married each other more randomly, poverty levels would be considerably lower than they are now. If we abandoned all current family arrangements and randomly grouped all Bolivians into new families of 5 persons, poverty levels would fall by about 15 percentage points (from the current level of 55% of all households to about 40% of all households). The Gini coefficient measuring inequality would also fall from about 0.70 to 0.55 (1) 1.

But Bolivians do not mix much in marriage. The correlation between partners' education levels is extremely high at about 0.77, with no signs of falling (2) 2. For comparison, the corresponding number for Germany is 0.52 and for Britain it is 0.41 (3) 3.


But not all Bolivians are equally restricted in their marriage choices. In the department of Santa Cruz the correlation is only 0.69 while in Potosi it is 0.82, with a corresponding difference in poverty rates (see Figure 1).

Why such differences?


My first guess was that in the warm regions, where people are more scantily clad, people marry more based on good looks than on education levels, whereas in the highlands, people are so covered in clothing that looks matter little, and you have to choose based on some other criteria.


But I think a better explanation is probably urbanization rates. In rural areas, young people tend to marry one of the neighbors' kids, which would likely have pretty much the same level of education. In urban areas, on the other hand, the pool of potential partners is vastly larger, and the likelihood of education differentials is larger. There is certainly a very strong negative correlation (-0.61) between marital sorting and urbanization rates (see Figure 2).
